MK9173-15CS08LFT

Overview

The MK9173-15CS08LFT is a Video Genlock PLL clock synthesizer manufactured by Integrated Device Technology (IDT), now part of Renesas Electronics. It provides analog PLL circuit blocks to implement frequency multiplication using an external divider in the feedback path, enabling high-frequency output from low-frequency inputs. The device integrates a phase detector, charge pump, loop filter, and VCO. Designed for video genlock applications, it operates on negative-going clock edges with a single 5V supply. The -15 variant outputs frequencies ranging from 0.625 MHz to 37.5 MHz. It features an on-chip loop filter, low-power CMOS technology, and comes in an 8-pin SOIC package.

Feature Summary

• Integrated analog PLL blocks including phase detector, charge pump, loop filter, and VCO
• Supports large frequency multiplication ratios via external feedback divider
• Optimized for video genlock systems with negative-edge triggered inputs
• Single 5V power supply operation with low-power CMOS technology
• On-chip loop filter eliminates external components for basic filtering

Applications

• Video generator lock circuits
• Synchronizing asynchronous video sources
• Generating video dot clocks from H-SYNC signals
• Digitizing video signals requiring stable reference clocks

Procurement Notes

Verify that the ordering suffix 'LF' confirms RoHS compliance and lead-free configuration as specified in the datasheet. Confirm the '-15' designation matches the required output frequency range of 0.625 to 37.5 MHz. Ensure the 'CS08' package code corresponds to the 8-pin SOIC form factor. Check if the 'T' suffix for tape and reel is needed instead of tubes, although the specific model provided implies tube packaging unless 'T' is appended.

Selection Notes

Select the MK9173-15 variant when the target output frequency must not exceed 37.5 MHz. The MK9173-01 variant supports up to 75 MHz. Both variants require an external digital divider (e.g., ICS674-01) in the feedback path to establish the multiplication ratio. Input reference frequencies must be between 12 kHz and 1 MHz. Ensure the application can provide a stable H-SYNC signal with low jitter for proper genlock operation.

Part Context

The MK9173-15 is pin and function compatible with the AV9173-15. Datasheet notes indicate that the AV9173-15CS08 and MK9173-15CS08 use the same die. IDT was acquired by Renesas Electronics Corporation. This component belongs to the family of video genlock PLL clock synthesizers designed for professional video synchronization tasks.

Replacement Considerations

The datasheet explicitly recommends the ICS673-01, ICS1522, or ICS1523 for new video genlock applications. The AV9173-15 is a direct functional equivalent sharing the same silicon die.
